Dwayne 'The Rock' Johnson's happy to do dad duty.

He's one of the toughest guys in showbiz but when it comes to his daughter Jasmine, Dwanye 'The Rock' Johnson is a total softie.

Posting a pic of himself changing his daughter's nappy, he writes: 'Regardless of where we are at when #2 happens with my baby girl ... I'm the #1 man for the job.'

The actor has been hands on since his daughter was born eight months ago - even if he gets to do it on a private plane!

He's the latest dad to get on the baby bandwagon, following Ryan Reynolds who, following the birth of daughter James, urged Seth Myers to get involved as a dad. 'Just do the dirty work, man. You gotta do diapers, you gotta do the middle of the night thing.'
